Dampness & Waterproofing
Dampness and Waterproofing
A high performance basement has the benefits of a healthier interior environment, reduced energy consumption, and a more durable and effective home. In order to achieve such standards, you must look at the condition’s involving the basement. The soil, in which your house is on, is critically important, as the soil types affect the way your property drains. Coarse grained soils, are good foundation soils, and drain freely. Fine grained soils, are typically weak founding soils, and drain poorly. According to the Ontario Building Code, the soil must assume a bearing capacity of 75 kpa. If you find yourself with a poor soil type, it is of the up most importance to abide by the code to prevent costly repairs and delays in the future.
Since we live in an environment that has vast temperature changes, and endure freezing, poorly built foundations can crack, which leads to water infiltration. Backfilling is important, both as to the method and materials used to avoid problems. Backfill soil should allow infiltrating water to drain to the drainage tile, as stated in the code “backfill shall be graded to prevent drainage towards the foundation after settling” 9.12.3.2 . Proper backfilling should start around the corners, then along shorter walls, and finally along the longer sections, this will help prevent stress cracking during backfill. Soil should be placed carefully, so you do not disturb the drainage tile and granular cover.
Maintaining a dry basement requires an effective strategy to deal with moisture is developed before the foundation is erected on site. The drainage system, which includes foundation all drainage, dampproofing, and drainage tile, controls and channels water away from a building, preventing water from migrating through the foundation to the
